Top RAM compartment

Here is your second chance to modify your RAM configuration. As before, there are two DDR3 SDRAM slots. Here they are stacked on each other, not side by side like the bottom. You may install up to 8 GB in each slot, allowing for 16 GB of RAM total.
If your computer has a dual-core processor, these are the RAM slots that will work.
